Non-Destructive Wood Moisture Meter (Moco II) — No Longer Manufactured
The HM530, also known as the Moco II, measured wood moisture through surface contact using high-frequency capacitance, leaving no pin marks. It has been replaced by the HM540, which carries the same non-destructive method forward with a wider species range and added data logging.
Non-marking measurement: read moisture through the surface without driving pins into the wood.
Wide range: 2 to 150% moisture content across more than 400 species.
Replaced by the HM540: the current model adds 999-point memory, USB logging, and JHWTC certification.
Handheld Pin-Type Wood Moisture Tester — No Longer Manufactured
The MT100 was a compact, handheld resistance moisture tester for woodworkers, lumber handlers, and shop environments. It read moisture by needle probe across a broad working range, with selectable calibration and a built-in correction chart for species variation.
Pin-type resistance: Direct moisture reading via needle probe penetration
Broad working range: 6–40% moisture content on a dry basis
Pocket-portable: 280 g with simple two-AA power for shop or field use
Analog Pin-Type Wood Moisture Meter — No Longer Manufactured
The AW-MO was a rugged, analog wood moisture meter built around a 4-needle probe and a direct-reading meter scale. With no display electronics to set up, it gave a fast moisture reading the moment the probe was driven into the wood.
Analog simplicity: Direct needle-gauge reading with zero menus or modes
4-needle probe: Penetrating resistance measurement for solid lumber
Field-rugged: Battery-checked, strap-equipped, built for the yard and the shop
